Description

A needle and skin treatment device for skin treatment with energy uniformity wrinkles {NEEDLE FOR SKIN TREATMENT WITH WRINKLES FOR UNIFORM ENERGY SUPPLY AND SKIN TREATMENT DEVICE}

The present invention relates to a needle for skin treatment, and in particular, it is possible to minimize damage to the epidermal layer and supply energy to various depths within the skin according to the purpose of the treatment, but the supplied energy is not excessively focused and has a uniform distribution, thereby speeding skin regeneration. It relates to a needle for skin treatment and a skin treatment device that can increase the value and shorten the treatment period.

In general, the skin covering the entire body is largely composed of three layers: the epidermal layer, the dermal layer, and the subcutaneous fat layer.

Among them, the epidermal layer is the layer on the most surface of the skin, and is composed of several layers such as the stratum corneum, the transparent layer, the granule layer, the play layer, and the base layer according to their location and function, and they are responsible for protection, defense and secretion.

In addition, the dermal layer is located under the epidermal layer and is located adjacent to the base layer to form most of the skin.Moisture, proteins, sugars, mucopolysaccharides, minerals, inorganic salts, etc. are in a jelly state, and capillaries related to blood circulation It is composed of a papillary layer, where the lymphatic vessels that carry lymph and lymph are located, and a reticular layer containing collagen, a collagen fiber related to wrinkles in the skin, elastin, an elastic fiber that gives elasticity to the skin, and a matrix (water reservoir).

Recently, as energy such as high-frequency current is directly delivered to the dermal layer of the skin through a needle to activate cellular tissues, a method of maintaining elastic skin and minimizing skin aging has been in the spotlight.

<First Example>

1 is a perspective view of a needle for skin treatment according to a first embodiment of the present invention, and FIG. 2 is a longitudinal sectional view for explaining the configuration of a needle for skin treatment according to a first embodiment of the present invention.

As shown, the needle 100 for skin treatment according to the first embodiment of the present invention is an insulating material harmless to the human body such as parylene or Teflon so as to surround the needle body 110 and the outer surface of the needle body 110 It comprises an insulating film 120 coated with.

In addition, some areas of the insulating layer 120 are removed by micromachining etching to form a conductive part 110b differentiated from other parts. In the conductive part 110b, a needle body 110 is formed by micromachining etching. It has a wrinkle (111).

The conductive part 110b provided as described above can be differentiated from other portions of the needle body 110 coated with the insulating film 120 to form a relatively strong electric field, and a higher intensity energy can be applied to the skin. Further, when a plurality of wrinkles 111 are formed in the conductive part 110b, the electric field is not focused to any one place in the conductive part 110b, and is formed to have a uniform distribution. The effect obtained by forming the wrinkles 111 will be described in more detail later.

Although only one conductive part 110b may be formed on the outer circumferential surface from the front end 110a to the rear end of the needle body 110 depending on the purpose of the procedure, a plurality of conductive parts 110b are preferably formed in a form spaced apart from each other as shown. The conductive part 110b is formed over the entire 360 degrees in the circumferential direction of the outer peripheral surface of the needle body 110 as shown. In this way, when a plurality of conductive parts 110b formed at 360 degrees are provided on the outer circumferential surface of the needle body 110, an electric field is simultaneously formed at a plurality of points in the skin where the needle is inserted, so that energy can be applied to the skin tissue in an almost omnidirectional manner. do.

The wrinkles 111 are formed by micromachining etching on the needle body 110 in the conductive portion 110b. The wrinkle 111 is made by concave semi-circular wrinkle bone (111a) is formed continuously, but the connection line (111b) between the wrinkle bone (111a) and the wrinkle bone (111a) protrudes as seen from the enlarged portion of FIG. It is sharply formed in the shape. If the wrinkles 111 are formed in a shape in which the concave semicircular wrinkles 111a are not continuously formed but convex semicircular projections are continuously formed, the connection line 111b may not be formed in a sharply protruding shape.

According to the configuration of the present invention, since the electric field tends to be mainly focused on the angled corners, a stronger electric field is formed around the connection line 111b formed in a sharply protruding form by the concave semi-circular corrugated bone 111a, Since there are many connecting lines 111b of such corrugated bones 111a even when viewed only within one conductive part 110b, the electric field is uniformly distributed with high intensity as a whole, as can be seen through the graphs of FIGS. 3 and 4. It has a shape. Accordingly, strong and uniform high-quality energy can be applied to the skin.

If, unlike the first embodiment of the present invention, only the conductive part is formed on the needle and the wrinkle 111 is not formed in the comparative example, as can be seen through the graphs of FIGS. 5 and 6, the formation of the conductive part Therefore, the electric field is excessively concentrated only at the ends of the conductive portions having the angular shape, and the electric field is formed too low in the other portions, so that the electric field is distributed unevenly as a whole. Referring to FIG. 7 comparing such a first embodiment and a comparative example, the impressive action and effect of the wrinkles 111 in the first embodiment of the present invention can be confirmed. In FIG. 7, it can be clearly seen that the conductive portion 110b of the first embodiment in which the wrinkles 111 are formed generates an electric field of higher intensity than the conductive portion of the comparative example without wrinkles, and shows a uniform distribution throughout the conductive portion 110b.

Therefore, in the case of the needle according to the first embodiment of the present invention having the wrinkles 111 in the conducting portion 110b, it is much more advantageous to control the intensity and amount of energy applied to the skin because the electric field can be uniformly formed. Therefore, it is possible to implement a high-quality skin treatment.

Here, the corrugations 111a of the corrugations 111 are formed by micromachining etching and are formed to a depth of 1/4 or less of the diameter of the needle body 110. More specifically, the depth of the corrugated bone 111a is preferably formed to be 5 to 15 micrometers in consideration of the diameter of the needle body 110. If the depth of the wrinkles 111a of the wrinkles 111 exceeds 1/2 of the needle diameter, the needle body 110 may be easily broken, and the depth of the wrinkles 111a of the wrinkles 111 is 5 microns. In the case of less than a meter, it is difficult to form a sufficient level while showing a distinct difference in the strength of the electric field compared to other parts.

The tip portion 110a of the needle body 110 is formed in a sharp shape so as to be easily inserted into the skin, and the tip portion 110a is preferably formed by coating an insulating film 120. However, since the needle body 110 itself is formed with a thin thickness, the tip portion 110a does not necessarily have to be sharply formed in order to be inserted into the skin, and the insulating film 120 is necessarily coated on the sharp tip portion 110a. It is also not limited to be formed with. However, it is preferable that the rear end of the needle body 110 is coated with an insulating film 120 to protect the skin layer. This is to help shorten the regeneration period after the procedure by not applying energy by an electric field to the epidermal layer of the skin that is directly exposed to the external environment, and to prevent the traces of the treatment through the epidermal layer from being exposed to the outside during the regeneration period after the procedure. .

In addition, although it is shown that the needle body 110 is solidly formed in the drawings, it may be formed hollow for the purpose of drug injection. With respect to the shape of the needle body 110, although the cylindrical shape is preferable as shown in the drawing, it is not limited to be formed in the shape of a prism having a polygonal cross section. In particular, in the case of the directional needle described in the second embodiment later, such a prismatic needle body can advantageously act.

8 is a perspective view illustrating a skin treatment apparatus to which a skin treatment needle according to the first embodiment is applied.

As shown, the skin treatment apparatus to which the needle for skin treatment according to the first embodiment of the present invention is applied includes a support member 200 and a needle array comprising the needle 100 of the first embodiment described above.

The support member 200 has a detailed configuration that can be applied to the needle body 110 by receiving power, but since such a configuration is known, a detailed description will be omitted.

In the drawing, the needles are arranged in two rows on both sides of the lower portion of the support member 200, but a plurality of needles are arranged in a more diverse manner, so that the needle array is not limited. In particular, in the case of the skin treatment needle according to the first embodiment, since the conductive portion 110b and the wrinkle 111 are formed in a 360-degree circumferential direction on the outer peripheral surface of the needle body 110, an omni-directional needle close to omnidirectionality in forming a magnetic field Therefore, it can be placed relatively freely.

9 is a flow chart illustrating a manufacturing method for manufacturing a skin treatment needle according to the first embodiment.

As shown in FIG. 9, the needle for skin treatment according to the first embodiment of the present invention is manufactured through a pretreatment step, an insulating film coating step, an insulating film etching step, a conductive part etching step, and a needle washing step.

In the pre-treatment step, a rod-shaped needle body 110 having a sharp tip portion 110a purchased or prepared in advance is washed with water and an acidic cleaning solution, and dried.

In the insulating layer coating step, the insulating layer 120 is coated on the pretreated needle body 110. The coating of the insulating film 120 may be performed using a chemical vapor deposition method. The material of the insulating film 120 is provided with parylene or Teflon, which is safe for the human body.

In the insulating layer etching step, the conductive portion 110b is formed by removing the insulating layer 120 in a predetermined region. To this end, when the insulating layer 120 is removed by etching along the circumferential direction of the needle body 110, the outer peripheral surface of the needle body 110 is exposed, thereby forming the conductive portion 110b. In the insulating layer etching step, the insulating layer 120 is easily removed by loosening the binding of the insulating layer 120 to the needle body 110 by applying thermal energy to the insulating layer 120 prior to micromachining etching. The operation of forming the conductive portion 110b by partially removing the insulating film as described above may preferably be performed by micromachining, but may be performed in various ways.

In the conductive part etching step, a plurality of wrinkles 111 are formed by performing micromachining etching while rotating 360 degrees with respect to the outer circumferential surface of the needle body 110 exposed in the conductive part 110b. At this time, the concave semi-circular corrugated bone 111a is continuously formed by micromachining etching, but the corrugated bone 111a and the corrugated bone 111a are directly adjacent to each other without a space between the corrugated bone 111a and the corrugated bone 111a. The connecting line 111b between them is formed in a sharply protruding shape. As described above, an electric field having a higher intensity can be formed at a plurality of points through the sharply protruding connection line 111b.

In the needle washing step, residues generated through a micromachining etching process on the insulating layer 120 and the needle body 110 are removed.

In the following, other embodiments modified in various forms will be described. For reference, reference numerals for each part are used as they are for parts or components corresponding to the first embodiment.

<Second Example>

10 is a perspective view of a skin treatment needle according to a second embodiment of the present invention, and FIGS. 11 and 12 are bottom views for explaining a skin treatment apparatus to which a skin treatment needle according to a second embodiment of the present invention is applied to be.

As shown, the needle according to the second embodiment has a directionality instead of having a conductive portion 110b having a corrugation 111 formed over 360 degrees in the circumferential direction of the outer circumferential surface of the needle body 110 compared to the first embodiment. It is characterized in that it is a directional needle (100A) formed only in one direction of the outer peripheral surface of the needle body 110 to have.

According to the configuration of the second embodiment, since the conductive parts 110b of all of the needles can be arranged to face the affected area when configuring the needle array in the skin treatment apparatus, a high-intensity procedure that applies energy more intensively to the affected area of the skin. It becomes possible to implement.

For example, in the case of the skin treatment apparatus shown in FIG. 11, each needle installed on the lower surface of the support member 200 is provided as a directional needle 100A, and each needle is disposed around the central part where the affected part is located. It shows a unique configuration with 110b) facing the center. According to this configuration, it is possible to apply energy intensively to the affected area while the conductive portions 110b of all the directional needles 100A face the central portion of the installation surface of the support member 200.

In the drawings, the needle body 110 is shown to be solidly formed, but may be hollow for the purpose of drug injection. With respect to the shape of the needle body 110, although the cylindrical shape is preferable as shown in the drawing, it is not limited to be formed in the shape of a prism having a polygonal cross section. In particular, in the case of the second embodiment, since the needles are provided as directional needles 100A, a prismatic needle body is advantageous if the side of the needles are arranged to face a specific direction.

In addition, in the case of the skin treatment apparatus shown in FIG. 12, a directional needle 100A is installed around the center of the installation surface of the support member 200 as shown in FIG. 11 so that the conduction part 110b faces the center of the installation surface. There is a difference in that the omni-directional needle 100 is installed without leaving it empty. In the case of a configuration in which the directional needle 100A and the omni-directional needle 100 are combined, it is advantageous because the omni-directional needle 10 can be inserted in the center of the affected area when the affected area is relatively wide.

The remaining configurations not described in relation to the configuration of the second embodiment are substantially the same as those of the first embodiment, and thus detailed descriptions will be omitted.

<Third Example>

13 is a perspective view of a needle for skin treatment according to a third embodiment of the present invention, and FIG. 14 is a longitudinal sectional view of a needle for skin treatment according to a third embodiment of the present invention.

As shown, in the needle according to the third embodiment, a plurality of conductive portions 110b having a wrinkle 111 are spaced apart from each other on the outer circumferential surface of the needle body 110 compared to the first embodiment, and the needle body 110 ) Is formed to have a wider front and rear width from the rear end to the front end 110a, and the depth of the wrinkle bone 111a is also formed deeper, so that the deeper the insertion depth into the skin, the stronger the electric field can be formed. do.

According to the configuration of the third embodiment, a portion of the needle that is deeply inserted into the skin generates a relatively strong electric field to apply high intensity energy, while a relatively weak electric field is formed in a narrow area near the skin layer to apply low intensity energy. can do. As a result, it is possible to differentiate the intensity of the procedure to such an extent that a high-intensity procedure is performed deep inside the skin, but almost no mark is displayed near the epidermal layer of the skin exposed to the outside. In this way, the procedure of the epidermal layer exposed to the outside can proceed the fastest.

The remaining configurations that are not described in relation to the configuration of the third embodiment are substantially the same as those of the first embodiment, so a detailed description thereof will be omitted.

<Fourth Example>

15 is a perspective view of a needle for skin treatment according to a fourth embodiment of the present invention, and FIG. 16 is a side view of a needle for skin treatment according to a fourth embodiment of the present invention.

As shown, the needle according to the fourth embodiment is characterized in that compared to the first embodiment, the needle does not have an insulating film 120 and is directly subjected to micromachining etching on the outer peripheral surface of the needle body 110 to form a wrinkle 111 To do. In this fourth embodiment, the conductive portion 110b becomes a region where the wrinkles 111 are formed.

According to the configuration of the fourth embodiment, there is no need for a process for forming the insulating layer 120 and a separate process for forming the conductive portion 110b during the manufacturing process, and the micromachining etching process is reduced to one time. Therefore, there is an advantage in that the manufacturing method is simplified.

However, in the case of the configuration according to the fourth embodiment, the strength of the electric field formed in the conductive part 110b and other parts of the needle body 110 is not large. There is a drawback of being somewhat difficult when trying to differentiate and apply high-intensity energy.

The remaining configurations that are not described in relation to the configuration of the fourth embodiment are substantially the same as those of the first embodiment, so a detailed description thereof will be omitted.

<Fifth Example>

17 is a perspective view of a needle for skin treatment according to a fifth embodiment of the present invention, and FIG. 18 is a side view of a needle for skin treatment according to a fifth embodiment of the present invention.

As shown, the needle according to the fifth embodiment is configured to compensate for the disadvantages according to the fourth embodiment, and the concave portion 110c having a shape recessed by etching using micromachining on the outer peripheral surface of the needle body 110 ) Is formed. Due to the formation of the concave portion 110c, the remaining portions protruding naturally constitute the conductive portion 110b. Here, the conductive portions 110b and the concave portions 110c are alternately disposed in the front and rear directions of the needle body 110.

The concave portion 110c is formed to have a front and rear width of 100 to 300 micrometers, and comes into contact with the skin, but has a lower contact strength than the conductive portion 110b having a protruding shape.

A plurality of wrinkles 111 formed by secondary micromachining etching are provided on the conductive part 110b. The wrinkles 111 formed on the conduction portion 110b are formed into wrinkles 111a having a depth of 5 to 15 micrometers.

When the needle according to the fifth embodiment is inserted into the skin, both the concave portion 110c and the conductive portion 110b are in direct contact with the skin, but they are in contact with the skin at different contact strengths, making a difference from each other. At this time, the conductive part 110b applies energy by an electric field in a state in which it is in relatively strong contact with the concave part 110c. At this time, although the conductive part 110b has a protruding shape, since the plurality of corrugations 111 serves to evenly distribute the electric field, there is no need to worry about the problem that the electric field is excessively focused at the edge of the conductive part 110b.

In the case of the fifth embodiment, the conductive portion 110b is formed in a shape surrounding the outer circumferential surface of the needle body 110 by 360 degrees similar to the first embodiment, but this is modified so that the conductive portion 110b changes one direction as in the second embodiment. It can also be directed toward. To this end, in the process of etching the concave portion 110c, the conductive portion 110b formed in a ring shape through an additional etching operation may be reduced to an island shape facing one direction as in the second embodiment.

In addition, as in the third embodiment, a plurality of conductive portions 110b are formed to have a wider front and rear width from the rear end of the needle body 110 to the front end 110a by modifying the fifth embodiment. By forming a deeper depth, a stronger electric field can be formed as the depth of insertion into the skin increases.

In the case of the remaining configurations that are not described in relation to the configuration of the above-described fifth embodiment, a detailed description will be omitted since they are substantially the same as those of the previous embodiments.

<Sixth Example>

19 is a perspective view of a needle for skin treatment according to a sixth embodiment of the present invention, and FIG. 20 is a side view of a needle for skin treatment according to a sixth embodiment of the present invention.

As shown, the needle according to the sixth embodiment differs from the fifth embodiment in that the conductive portion 110b is formed in a concave shape from a protruding shape. In this case, etching is performed using micromachining to form the concave-shaped conductive portion 110b.

The conductive portions 110b are formed to have a front and rear width of 100 to 300 micrometers, and are provided in a form in which a plurality of the conductive portions 110b are spaced apart from the outer peripheral surface of the needle body 110. A plurality of wrinkles 111 formed by secondary micromachining etching are provided on the surface of the conductive portion 110b. The wrinkles 111 formed on the conduction portion 110b are formed into wrinkles 111a having a depth of 5 to 15 micrometers. Such a conductive part 110b comes into contact with the skin with a relatively low contact strength compared to other parts.

In the case of the needle according to the sixth embodiment, energy is applied by an electric field while the conductive portion 110b has a relatively low contact strength compared to other parts and is in contact with the skin. At this time, since the plurality of corrugations 111 formed in the conducting portion 110b serve to uniformly distribute the electric field, there is no need to worry about the problem that the electric field is excessively focused at the edge of the conducting portion 110b.

Even in the case of the sixth embodiment, the conductive portion 110b is formed in a shape surrounding the outer circumferential surface of the needle body 110 by 360 degrees similar to the fifth embodiment. It may be directed toward one direction, and as in the third embodiment, a plurality of conductive portions 110b are formed to have a wider front and rear width from the rear end of the needle body 110 to the front end 110a. ) Can also be formed deeper so that the deeper the insertion depth into the skin, the stronger the electric field can be formed.

The remaining configurations that are not described in relation to the configuration of the sixth embodiment described above are substantially the same as those of the previous embodiments, so a detailed description thereof will be omitted.

Although the preferred embodiment of the present invention has been described above, the present invention can use various changes, modifications, and equivalents. It is clear that the present invention can be applied equally by appropriately modifying the above embodiments. Therefore, the above description does not limit the scope of the present invention determined by the limits of the following claims.

110: needle body 110a: tip (of needle body)
110b: conduction part 110c: concave part
111: wrinkle 111a: wrinkle bone
111b: connection line 120: insulating film
